OK could have been better
The lag after the forest stage is very noticeable even on a dell optiplex 745. The upgrades mostly are worthless. The cloud attack only speeds up by a fraction of a second from when it is maxed as compared to when it is at starting level. The cloud barrier is durable at first until you come to the last area and ahve to deal with the wrestler. The other enemy with a rocket takes half your life away but only takes on hit to kill but good luck as the enemies bunch up and it is hard to hit it. There is a 3 second delay in firing the thunder attack and let me tell you there is nothing more irritating than hammering the S key trying to get it to fire when your little girl is being assaulted as you are now out of cloud barriers that disappear after one hit from the wrestler and she dies before the game even registers the attack. I swear I lost the last level twice just due to that delay.
Also the keys for these attacks are too close together. Attempting to hit the cloud barrier button and hitting S and wasting a lightning attack is incredibly irritating.
Some things that could have been improved: Ability to jump while carrying the girl, no dealy in lightning attack (you already charged it up so whats the deal?), nerf the rocket bomber, space out attack keys and remove the lag.
